I was wondering if someone could point me to the largest FUDforums currently running. That is....what site has an instance of FUD running with the most forums/posts. I am very curious how the forum functions under extreme loads (holding several hundred thousand, or even several million, messages across multiple forums).

So how big can FUD go? Are there actual real-world examples of FUD installations with post counts into the millions?

Can someone point me to a FUDforum wich is large in terms of users online (not number of messages, registered users, ...)?
I'm speaking of about 1k users online during a 15min session.
All FUDforum installation I saw until now were tiny ones with no more than 100 users online in parallel.

I know that FUDforum performs well with a few dozen users even on smaller webservers, but there's no experience how it behaves on a high-volume site.

Looking at the list of logged-in users at these forums, this doesn't appear to be big (e.g. currently "There are 0 members(s), 0 invisible members and 8 guest(s) visiting this board." on Sun Java Enterprise System Forums).
It's nevertheless impressive that Sun uses FUDforum.

There are several other large users, of the forum, but I am under NDA not to disclose them. However, because they are online creative use of Google (or any other search engine) can be used to locate them.
